A wig is just some fake hair. You can get wigs in almost any colour, either brightly coloured ones like in the picture, or natural coloured ones that look like real hair. Some people wear wigs for fun, others wear them because they are bald and don't want other people to know.
A wig that only covers part of your head is called a toupee.
Something is wild if people haven't changed it to suit their own needs. Wild animals and plants live or grow anywhere they are able, and don't rely on people to feed them and look after them. The opposite of wild is domesticated. Wild versions of household flowers, fruits and vegetables generally have much smaller fruits or flowers than their domestic varieties.

The willie wagtail, or willy wagtail, is a small, black and white songbird found in Australia and Indonesia. They are called wagtails because of their habit of waggin their tail backwards and forwards as they hop around. They eat insects, and are a common sight in backyards in Australia. They are aggressive and can be seen chasing larger birds and even cats out of their territory.
